Abstract (German)
Ziel der vorliegenden Arbeit war die Entwicklung neuer Syntheserouten zur Darstellung von neuen Alkaloiden Botryllazin B (2) und (4-Hydroxyphenyl)-[4-(4-hydroxyphenyl)-1H-imidazol-2-yl]methanon (3) und deren Derivaten. Als Vorstufe zur Herstellung der beiden Alkaloide verwendeten wir 4-substituierte Oxoacetaldehyde 10-12, die im Falle von (4-Hydroxyphenyl-[6-(4-hydroxyphenyl)pyrazin-2-yl]methanon ...

Translation of the abstract (English)
The pyrazine- and imidazole-derivatives, whose synthesis was studied in the following, contain to a class of natural occurring alkaloids which were first isolated from the red ascidian Botryllus leachi by Duran et al..1 The authors described furthermore some - in particular specific - cytotoxicity against four tumor cell lines. In order to obtain these alkaloids on a synthetic route and to get ...
